Well, I did but there may be more areas to deal with. See above.

The BUG plus is you actually got boost down into the usable rpm range.

Oh, for sure, WeeYari! I was so happy to see that. Now 1 - 2 psi doesn't make a huge difference, but it's definitely pulling harder. At 4 psi it's pretty strong. Once I get to my full 8, it should be even more fun!

I found this calculator a long time ago and just recently started plugging numbers in again. It is a simplified calculator, but a good reference anyway. It also seems right in line with my dyno results. Ultimately, I don't care what my numbers are as long it's working to its potential and is safe.

My Corolla engine should put out 126 crank HP stock, due to the xD (detuned, I think) ECU. With a 15% (the average, I guess) driveline loss, that would result in about 107 whp. Assuming 5.4 psi (which the tuner got, not sure how, lol), that equates to 146.32 whp. That's bang on with my dyno numbers.

At 8 psi, I should be able to expect ~165 whp. I think that should suffice in the light little Yaris, haha.

I had a long chat with a member of Toyota Nation a couple of evenings ago. He has the same kit and apparently he dyno'd 195. The kit claims to add 90 - 100 hp to the Corolla, so not sure what all is at work with mine.

Anyway, here's the very simplified boost calculator:

It's important for me to keep my expectations in check and understand fully what this is. I've driven in muscle cars and a friend had a Porsche 930 turbo that was an under 5 second 0 - 60 car. The turbo Yaris will never be this, but it will be very fun to drive.
